Product overview
The RadioLink AT10II is a handheld radio-control system for aircraft and other remotely controlled models. Its 12 individually configurable channels, 15 model memories and programmable standard and curve mixing support different control arrangements, including helicopter, fixed-wing and multirotor applications. The radio combines DSSS and FHSS with 16-channel pseudorandom hopping and QPSK modulation. All 12 channels have a stated synchronous 3ms response. With the standard R12DS receiver, the specified airborne control distance is 4000m in an outdoor open area without interference; actual distance depends on flight conditions.
The transmitter measures 180 × 95 × 220mm and weighs 0.95kg. Textured grips, adjustable stick length and selectable left- or right-hand throttle accommodate operator preferences. The standard R12DS provides simultaneous SBUS and PWM outputs, while alternative receivers offer different signal interfaces and installation sizes. The battery compartment measures 115 × 32 × 30.5mm and includes an AA battery holder. Power enters through a JST connector at 7.4–15V, with electronic reverse-polarity protection. An 18650 battery arrangement requires a JST plug and must fit the compartment.
The supplied package contains a transmitter, receiver, propulsion-battery voltage telemetry module, neck strap, spare throttle-centering accessory, sticker and manual. Receiver telemetry provides signal strength, RSSI and receiver voltage. PRM-01 adds propulsion-battery voltage with R9DS or R12DS receivers; optional PRM-03 connects supported receivers and flight controllers for additional flight information. Simulator use requires a dongle through the rear PPM port or a PPM receiver. USB firmware upgrades have motherboard-specific operating-system and file-format requirements. Audible and text alarms cover low RSSI and low transmitter, receiver and propulsion-battery voltage.
